Inventor: YAMAMOTO SHOJI
IPC: B22F3/02
Filed: 1995-04-28
Abstract: PURPOSE: To provide a sintered compact good in density and appearance by setting a degreasing condition so that the carbon amt./oxygen amt. of a degreased brown body when a recycled material is used is equalizied with the carbon amt./oxygen amt. when a virgin material is used and injection- molding the brown body.

In this case, the degreasing condition is set so that the ratio of the carbon amt. to oxygen amt. (carbon amt./oxygen amt.) contained in a degreased brown body is approximately equalized to the carbon amt./ oxygen amt. of a degreased brown body when a virgin material is used. For example, the maximum degreasing temp. is lowered to compensate for a decrease in the carbon amt. in recycling and to reduce the increased oxygen amt. Otherwise, the maximum temp. heating time in degreasing is shortened to increase the carbon amt. in the brown body and to decrease the oxygen amt.
